Subscribed ! I have been looking for this style for years. I had the same appearing filters back in 78 , as I remember they were not that much of a performance tool but I just like the looks. This is the first I've seen except for some ebay rusty stuff! I would like to have the stacks in them, shouldn't be too hard to fab. Here is an old pic of my K8 in 1980, you can just make out the mushroom (Ramflo) filters.
